      Parameter

      Description

      Value

      Enable SmartThin

      If thin provisioning is enabled, the storage system dynamically allocates storage capacity to file systems based on the actual capacity used by hosts instead of allocating a preset capacity, achieving on-demand allocation.

      [Example]

      Enable SmartThin

      Reserve snapshot space

      After this option is selected, the system automatically selects a storage pool whose capacity is 130% of the required capacity. When you use the storage pool to create storage resources for applications, reserve sufficient space to create snapshots for applications.

    Storage Pool Policy

    The system sets storage pool allocation policies based on preset VMware parameters. The performance level of each VM is defined by High performance, Performance/Cost balance, Low cost, or Manual selection, described as follows:
    • High performance: The system automatically selects a RAID 6 storage pool containing SAS disks only. If such a storage pool does not exist in the system, create one.
    • Performance/Cost balance: The system automatically selects a RAID 6 storage pool containing SAS and NL-SAS disks only. If such a storage pool does not exist in the system, create one.
    • Low cost: The system automatically selects a RAID 6 storage pool containing NL-SAS disks only. If such a storage pool does not exist in the system, create one.
    • Manual selection: Users define storage pools that meet the VMware service requirements.

    [Example]

    Manual selection

    Selected Storage Pool

    Name of the storage pool automatically allocated by the system to a VMware instance.

    [Example]

    StoragePool001

  9. Optional: If no desired storage pools are available, click and modify Storage Pool Policy in the displayed dialog box, or click Create Storage Pool to create one. Table 4-6 describes related parameters.
  10. Optional: Assign the client the permission for the NFS share.
    1. Select a client that you want to set NFS share in Client Information.
